SpectrHA is a matlab tool to execute Fourier Spectral Analysis and Harmonic Least Squares Fit analysis of series.
It's designed to be used with the output of the oceanographic model ROMS
(Regional Ocean Model System), but can easily be changed to use any other sources.
Overview:
-You can do Fourier Analysis and Least Squares Fit Harmonic Analysis from the ROMS history file, ROMS stations file or any external serie.
-Least Squares Fit can easily be configured to any desired frequencies.
-SpectrHA can use T_TIDE to perform tidal analysis and prediction.
-Previously analyzed data can be loaded, for instance, as tidal ellipses and overlayed in your current analysis.
-A fast analysis of the grid used in the modeling (either SEAGRID file or ROMS output history file) is available, as well as analysis of vertical s-levels.
-Zhigang Xu tidal ellipse routines ap2ep and ep2ap are used and distributed.
-This software was created with MATLAB 6.0 in Linux SuSe 8.0.
I created SpectHA to make my work easier. Hope you find it useful.

Requirements:
- NetCDF interface for MATLAB, if you are going to use SEAGRID or ROMS files.
- T_TIDE, for tidal analysis and prediction.
